' WATCH-CASE BEZEL.

SPECIFICATION forming part of Letters Patent No. 299,369,'da.ted May 27, 1884.

Application filed December 1, 1883.

To all whom it may concern.-

Be it known that I, EZRA G. Frrou, of N ewton, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Watch-Case Bezels, of which the following is a specification.

This invention has for its object to provide improved means for securing glasses or crys tals to watclrease bezels; and it consists in a bezel composed of two parts detachably con nected, and adapted to clamp the margin of the glass and confine the same tightly, as'I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a View of the inner side of a bezel embod'y- Fig. 2 represents a sec tion on line :0 m, Fig. 1. Figs. 3 and 4 represent sectional views of the parts of the bezel disconnected. Fig. 5 represents a section of a modification.

The same letters of reference indicate the same parts in all the figures.

In carrying out my invention I construct a bezel in two parts, ab. The part a constitutes the body orv main portion of the bezel, and is adapted to be secured to the watchcase by means of an internal screw-thread, c,

and has a seat or bearing, a, for the beveled margin of the glass d, said seat being preferably reduced to a thin edge, as shown in Figs. 2 and 3. The part b is a ring or follower, which is externally threaded at b, and screwed into the threaded portion of the part a, and has a shoulder, I)", adapted to bear against the inner surface of the glass and force the latter against the seat a. The glass placed on the seat or hearing a is forced firmly against said seat by the pressure of the follower b when the latter is screwed into the part or body a. The thinness of the seat a enables it to conform to any inequalities in the beveled edge of the glass, so that if the glass is not perfectly circular, as is often the case, the seat a will bear closely against it at all points.

It will be observed that the described construction of the bezel enables the glass to be easily applied and perfectly fitted, and that the same bezel is adapted to hold glasses of (No model.)

different sizes, the adjustability of the follower I) enabling it to be set back from the seat a to hold a larger glass and to be moved toward said seat to hold a smaller glass.

Heretofore glasses have always been snapped or sprung into beze'ls, and much difficulty has been experienced in fitting them properly, as is well known to every watch-maker, the glassholding seat in the bezel, as heretofore made, being practically unyielding and requiring a glass of an exact given size.

The operation of snapping a glass into a bezel is liable to break the glass, and in most cases the glass is loose after it is inserted, and requires to be tightened by the use of cement.

It will be seen that my improvement entirely obviates the objections to the common method of inserting glasses, and enables a glass to beinserted by a person not skilled in the art.

The follower b is preferably provided with a reflector, b Orifices 0 0 are provided in the followerb to receive a spanner or other suitable tool to turn the follower. The threaded portion of the part or body a serves both to secure the follower b and .to secure the part a to a threaded shoulder on a watch-case center.

While the construction described and shown is the best of which I am at present aware, I do not limit myself to said construction in all its details. For example, the seat a may be rigid, if preferred, and the follower may be secured to the body a, and pressed against the glass by other means than screw-threads. The inner part, b, may be the body of the bezel adapted to be screwed to the case, the seat a being screwed to the part I), as shown in Fig. 5.

The body of the bezel maybe provided with a snap edge to fit a shoulder on the case, instead of being threaded.

I olaim 1. A watch bezel consisting of two parts screwed together, and clamping between them the beveled edge of the crystal, the face of which is beyond the outer part of the bezel, substantially as described.

2. A watch-case bezel composed of two metallic parts detachably connected, one of said parts having a flexible seat adapted to conform to inequalities in the margin of the glass, as set forth.

3. In a watch-oase bezel, the outer portion or body, a, adapted to be applied to the case, and having a flexible seat for the margin of the glass, combined with a device for pressing and holding the glass against said seat, as set forth.

4. A watch-case bezel composed of the outer portion or body, a, internally threaded, and provided with a flexible seat, a, for the margin of the glass, and the inner part or follower threaded to enter the threaded portion a, and provided with a shoulder adapted to bear against the inner surface of the glass, the ar- 15 EZRA C.
